Abstract

An insecticide-impregnated fabric that remains sufficiently effective at killing and repelling disease vector insects after repeated washings with detergent and water is described. The fabric is impregnated with an insecticide composition containing an insecticide, a cyclodextrin, and a binding agent. The resulting fabric is useful for providing personal protection against disease-carrying insect vectors, particularly when assembled as a bednet in regions of the world where malaria is prevalent, and will remain effective for a longer period of time before re-impregnation is necessary.
